Jonathan, of course you are right that the illegal aliens who cross the border in search of honest work are not the same as the predators described in the MacDonald article. Nevertheless, the existence (tacitly accepted by the Feds) of a large population forced by the lack of documentation to exist on the margins of society must, surely, provide an ideal milieu in which such criminals can flourish. And no, the answer to the problem is not to hand out documents to everyone who asks.
